BQBBIN-CARRIER FOR WING-MACHINES Specification of Letters Patent.

Patented May 26, 1908.

Application filed June 22, 1905. Serial No. 266,517.

To will whom it i'rm'g concern:

Be it known that I, PAUL Ansoni'rrz, a citizen of the United Statr-as, residing in New York city, borough of Brooklyn, county of Kings, and State of NewTYor-k, have in vented certain new and useful Improve.- ments in Bollhi i-Carriere for Sewing-Maehines, of which the following is a full, clear, and exact specification.

My invention relates to certain new and useful improvements in hohhin carriers. Its purpose isto do away with the necessity of using specially shaped hohhins upon which the thread must he wound before placing it in a sewing machine is now the case in most d ouhle-threai'l machines.

By means. of my present invention it is possible to use ordinary s ools of thread as they are commercially so d in the trade by means of a specially designed spool or bobbin carrier which I lIQ-VGPI'OClUC-Qfl, and thus a great saving of time and labor is possible.

Uther features of my invention include the }'}TOYlS'l )I1 of a suitable tensiondevice to such a carrier and .ofautomatic spool ejecting 'mcanstherei'or, when the earner 1s opened for the purpose of replacing a spool from whih thethread has been used.

V lo my invention 1s adaptable to many kinds of machines it is particularly useful in connection with theniaohine' shown in Letters Patent No. 766,130 granted to me, July 26, 1904, and in the drawing l have illustrated it as applied to a machine of this type.

In these-drawings Figure 1 represents a erspeciive vieividi sofmuch of the looptin'niing. mechanism of the sewingmachine as is necessary'toshow the general applicatlon of my present invent on, the spoo carrier-heing. shownin-iloitod lines for the sake of .clearness. .F 2 shows a perspective view' of one form of spool carrier and Fig. 3 a top. view thereof. (Fig. l is a perspective view of a inodiiiecl'form of my invention and .Fig. 5a topview of the device of Fig. 4.

Fig. 10 is an inverted plan of the device of F igs. S and9.- Figs. l1 and 1.2 are end elevations thereof looking in diil'erent. directions, and Fig,- 13 is a yiow of a slightly modified form of thedevice of Fig. 9) showing the spool retainer open and the spool ejector.

- be inserted at either end.

Figs. 14, 15 and .16. are side, top and end views respectively of still another form of my invention, and Fig. 17 is a similar view-to Fig. 15 but showing the spool carrier open. Figs. 18 and 19 are detailed. views of the spring for holding the spool retainer in place.

Similar numerals of reference indicate like parts in all the drawings.

As will. be readily seen, my spool carrier or case comprises a thread guiding ring or frame 1, 1:)art of the peripheral edge of which is bifurcated and formed into ridges 2, 2 as shown in Figs. .3, 5, etc. The channel formed by these ridges is provided for the passage of the loop-taker '3, and loop-spreader 4, which are in every way similar to like parts in the I machine of my patent-before mentioned, and therefore neither they nor their" operation in the machine need he more particularly described herein.

The thread guiding ring is pear-shaped, slightly flattened upon one side, that it is larger in cross section nearer one end than the other, a'lthoughthe opposite sides of the pear-shaped portion are not symmetrical,

one being somewhatiiattened, and is particularly valuable as it affords the great est compactness possible in a device which carries a full size spool of thread and yet pernuts of a comparatively small loop to pass it.

At 'one end of thering, the thread guiding peripheral edge terminates in a ridge 1.6 which projects sli htly thereheyond and also projects laterally horn the side faces ofsaid ring, said ridge serving in connection with coperating mechanism inthe machine to always keep the ring in its rope r position.

In the device shown in igs. -2 and 3 the spool holder or retainer consists of-a-cylinder 5, which is pivoted at one end as at 6. In

this form the cylinder swings out at rightv angles and permits the spool to be inserted I therein, and when so inserted and theretainer swung home, the rounded end of a spring 7, enters a recess 8,- in the top of the cylinder and securely holds it in place. 'Figs. 4 and 5 show a somewhat similar con struction; but in this instance the spool re taining cylinder is pivoted at the center and swings upon such pivot so that the spool may In this form the retaining spring 7, contains an additional perforation 9 which permits of thepa's'sage of the pivot 6. l

Figs. 6 and 7 show a further modification shaped that upon the opening of the case. i-

scribed forms, and "have therefore characterized it an 5. One halt of the basket or spool retainer is hinged as shown in Fig. 9, and this half can be swung open to permit the insertion of a 8700i and when closed is held in this position y the spring arm 11, passing over the shoulder 12, as shown in Figs. 1 1 and 12. The spring arm 11 can usually be formed integral-with the swinging portion of the spool retainer as the metal will be found of su'liicient elasticity to be sprung in place I where it is rigidly retained.

In Fig. 13 I have shown the swinging portion of the retainer as pro'ridl-ad with a jection 1?? beyond the pivot'and this i projection bears upon the back of the spool and throws it out ofthe case and acts as a spool ejector. When the case is closed it lies inside the case and out of the way and does not interfere at all with the spool or thread.

The m'odi'lied form of my devicefFigs. 14 to 17 inclusive, show a similar basket having a swinging port-ion or cover 5, but in this form the cover is pivoted at the end instead of at the sides, and swings out as is shown in Fig. 17.. A small lug 11 is provided on the swin ing portion which engages a recess or shoulder 12 on the carrier and serves to hold it in a closed position as shown in Fig. 11. I likewise provide a small spring tension 14; which for convenience I rivet or otherwise secure. to the swinging cover as at 15, and before leading the thread i from the spool within the case to the machine it is passed under the said spring which. serves to maintain a sullicient tension on the thread .to pre vent the thread unwinding therefrom, and which aids in the formation of a pro or stitch.

It will be readily understood t rat many modifications and changes can be made in my invention from the particular forms shown without departing from the spirit thereof, and I do not limit myself to the parmg a b' urca'ted section extending part way around its circumference, a substanti-all cylindrical spool retainer positioned in'sai carrier and extending longitudinally thereof; the wall of said cylindrical retainer constituting the sole support for the spool to be clip ried freely, said cylindrical spool retainer having a swinging 'side wall whereby access may be had for inserting or removing the spool and a spool ejector carried by the swinging wall and adapted to throw out the spool upon the swinging of the side wall.

tainer being mounted for swinging mo 'e ment to all'ord access thereto.

3. A non-revo|uble spool or bobbin carrier pear shaped in cross section comprising a peripheral loop guiding ring lie-ring a oifurcated section extending part way around its circumference, a substantially cylindrical spool retainer positioned in said carrier and extending lrmgitudinally thereof. the wall of said cylindrical spool retainer t-l-nl lituting the sole support for the spool. nd; ed in be carried thereby, and said rylirnilnral spool retainer having a swinging side wall allording acccssthcreto, and acatrhlor retaining the swinging wall in place.

4. A non-re oluble spool or bobbin, rtni'llGI pear shaped in cross section comprising a peripheral loop guiding ring having a bifurcated section extending part way round its circumference, a substantially cylindrical SPOOl-l'fibllliltl' positioned in said carrier and said spool retainer constituting the sole sup port for the spool adapted to be carried thereby and said cylindrical spool retainer having a swinging side wall, affording access theretoand terminating at its end in a spool ejector.

5. A non-revoluble spool or bobbin carrier, pear-shaped in cross section comprising a peripheral loop guiding ring having a bifurcated section extending part way around its circumference. a substantially cylindrical spool retainer positioned in said carrier and extending longitudinally thereof, the wall of said cylindrical spool retainer constituting the sole support for the spool adapted to be carried thereby, and said cylindrical spool retainer having a swinging side wall affordin access thereto.

n testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
